Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, unless otherwise specified, the meaning of "plurality" is two or more.

[0068] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0069] like Figures 1 to 8 As shown, a double-wire drum winding device with a wire drum in front comprises:

[0070] A support column 1, wherein a front wire winding device 2 and a rear wire winding device 3 are respectively arranged on the front side and the rear side of the support column 1, and a wire cutting wire 4 is wound around the surfaces of the front wire winding device 2 and the rear wire winding device 3;

[0071] A storage table 5 is arranged at the front side of the support column and below the front wire winding device 2, and the storage table 5 is used to store the objects to be cut;

[0072] A wire cutting machine head 6 is arranged at the front side of the support column and located between the storage table 5 and the front wire winding device 2. The wire cutting machine head 6 is used for cutting the object to be cut;

[0073] A movable guide device 7 is arranged at the front side of the support column and is located beside the front wire winding device 2;

[0074] The wire cutting wire 4 passes through the rear wire winding device 3, the wire cutting machine head 6, the moving guide device 7 and the front wire winding device 2 in sequence;

[0075] The movable guide device 7 can move along the length direction of the front wire winding device 2 with the wire cutting wire 4;

[0076] The wire cutting wire is manually wound onto the wire storage drum, and the existing wire storage drum is set behind the wire cutting device; when the damaged wire cutting wire needs to be removed, the staff needs to go around the back of the wire cutting device to pull out the wire cutting wire, cut off the damaged wire cutting wire, and then pass the wire cutting wire through the wire cutting machine head, and then wind the wire cutting wire back to the wire storage drum. Due to the complex structure of the existing wire cutting device, it is troublesome to replace the wire cutting wire, resulting in a long winding time and low efficiency.

[0077] To this end, the double-wire drum winding device of the utility model is respectively provided with a front wire winding device 2 and a rear wire winding device 3, and the front wire winding device 2 and the rear wire winding device 3 can be differentially controlled by a program so that the wire cutting wire 4 is kept in a tensioned state, so that the wire cutting wire can be kept in a tensioned state, thereby realizing the wire cutting process. When the front wire winding device 2 rotates to reel in the wire, the rear wire winding device 3 rotates to release the wire, and when the rear wire winding device 3 rotates to reel in the wire, the front wire winding device 2 rotates to release the wire.

[0078] The use of this technical solution has the following effects:

[0079] 1. When it is necessary to insert a new wire cutting wire 4, the staff can release the wire cutting wire 4 through the rear wire winding device 3, wrap the new wire cutting wire 4 around the guide arm 11, and pass it through the wire cutting machine head 6, and fix the wire cutting wire 4 on the front wire winding device 2, so as to realize automatic updating of the cutting segment of the wire cutting wire 4. The operation is simple, and the staff does not need to go around the rear side of the wire cutting device to perform complicated operations of replacing the wire cutting wire, which shortens the winding time and improves the efficiency of replacing the wire cutting wire 4.

[0080] 2. When the middle section of the wire cutting wire 4 is worn and needs to be cut, if the worn position is close to the front winding device 2, the problematic wire cutting wire 4 can be put in front of the front winding device 2, and after cutting the problematic part and the part at the front winding device 2, one end of the cut wire can be tied to the front winding device 2 again. Of course, when the problematic part is close to the rear winding device 3, the wire cutting wire 4 at the rear winding device 3 can be cut. The repair work of the wire cutting wire 4 can be realized immediately without the cooperation of multiple people.

[0081] 3. In the present invention, the wire cutting wire 4 only needs to pass through the rear wire winding device 3, the wire cutting machine head 6, the movable guide device 7 and the front wire winding device 2 in sequence. At this time, the exposed length of the wire cutting wire 4 is shortened, so that the damage to the wire cutting wire 4 caused by unexpected situations in the processing environment can be effectively avoided, thereby ensuring the safety of the wire cutting wire 4.

[0082] 4. The existing wire cutting machine is only equipped with a single wire drum. When the wire drum is reversing cutting, the inertial guide direction of the wire cutting wire 4 is different from the rotation direction of the wire drum, which will cause the wire cutting wire 4 to shake and cause certain damage to the wire cutting wire 4. In the utility model, a front wire winding device 2 and a rear wire winding device 3 with a double wire drum structure are adopted. When the front wire winding device 2 retracts and rotates, the rear wire winding device 3 is driven to release the wire. At this time, the rear wire winding device 3 can balance the tension of the wire, avoid sudden pulling of the wire when reversing, and reduce wire shaking.

[0083] It is worth mentioning that, in the present invention, there is no restriction on the placement angles of the front wire winding device 2 and the rear wire winding device 3, and when the front wire winding device 2 is placed horizontally, the threading process of the new wire can be achieved more quickly.

[0084] In the existing wire winding device, the wire cutting wire 4 needs to be wound on the surface of the wire winding device layer by layer. For this reason, the existing wire winding device is provided with a moving mechanism. The moving mechanism drives the wire winding device to move when the wire winding device rotates, so that the wire cutting wire 4 can be wound on the wire winding device layer by layer. Although a front wire winding device 2 and a rear wire winding device 3 are provided in the utility model, the rear wire winding device 3 is an existing wire winding device, and the front wire winding device 2 is provided in front of the support column 1, and other devices such as a storage table 5, a wire cutting machine head 6, etc. need to be installed on the support column 1, so there is space in front of the support column 1. The mobile mechanism is not convenient to install due to the limitation of the size of the front winding device. Therefore, in order to solve the problem of the double winding device, a mobile guide device 7 is provided in front of the support column 1. The volume of the mobile guide device 7 is smaller than that of the front winding device 2, which is convenient for installation. Moreover, the mobile guide device 7 is tensioned with the wire cutting wire 4. When the front winding device 2 rotates, the mobile guide device 7 moves along the direction of the front winding device 2, so that the wire cutting wire 4 can be wound layer by layer on the surface of the front winding device 2, avoiding the wire cutting wire 4 from being knotted on the winding device and unable to rotate. This ensures that the double wire drum winding device with the double winding device can operate normally.

[0085] Preferably, the movable guide device 7 includes a guide rail column 7a, a first slider 7b, a first screw rod 7c, a power device 7d and a wire arrangement component 7e;

[0086] The guide rail column 7a is fixed to the front side of the support column 1, and a first guide rail 7aa is fixed to the surface of the guide rail column 7a. The first guide rail 7aa extends along the length direction of the front wire winding device 2, and a support plate 7ab protrudes outward from the end of the first guide rail 7aa.

[0087] The first screw rod 7c passes through the support plate 7ab, one end of the first screw rod 7c is a mounting end, and the other end is a power end, the mounting end is located beside the first guide rail 7aa, and the mounting end of the first screw rod 7c is parallel to the guide rail column 7a, the power device 7d is fixed to a side of the mounting plate 9 away from the mounting end, and the power device 7d is transmission-connected to the power end;

[0088] One side of the first slider 7b is slidably mounted on the first guide rail 7aa, a screw hole is opened in the middle of the first slider 7b, and the screw hole is adapted to be installed with the mounting end of the first screw rod 7c. The wire arrangement component 7e is fixed to one side of the first slider 7b, and the surface of the wire arrangement component 7e is wound with a wire cutting wire 4.

[0089] like Figures 2~4 As shown, when the double-wire drum winding device is used, the power device 7d is started, and the power device 7d is a motor that can rotate in both forward and reverse directions. When the power device 7d rotates, the first screw rod 7c is driven to rotate, and the first slider 7b moves up and down along the rotation direction of the first screw rod 7c. A wire arrangement component 7e is fixed on the first slider 7b, and the wire arrangement component 7e is tensioned with the wire cutting wire 4. At this time, the wire cutting wire 4 is lifted up and down driven by the wire arrangement component 7e. The front winding device 2 only rotates to wind the wire cutting wire 4 around its surface layer by layer, which will not cause the wire cutting wire 4 to overlap or knot, thereby ensuring the normal operation of the device.

[0090] Preferably, the wire arrangement component 7e includes a mounting block 7ea and a wire arrangement wheel 7eb, the mounting block 7ea is fixed to the first slider 7b, the side of the mounting block facing away from the first slider 7b is rotatably mounted with a wire arrangement wheel 7eb, and the wire cutting wire 4 is tensioned on the wire arrangement wheel 7eb.

[0091] In one embodiment of the utility model, the wire cutting wire 4 is tensioned by the wire row wheel 7eb, and the wire row wheel 7eb is rotatably mounted on the mounting block 7ea through the rotating shaft 7eba. When the front winding device 2 rotates, the wire row wheel 7eb is also driven by the wire cutting wire 4 to rotate, reducing the friction between the wire cutting wire 4 and the wire row wheel 7eb, thereby reducing the wear on the wire cutting wire 4. The service life of the wire cutting wire 4 is improved, and the first slider 7b can be detachably mounted on the first slider 7b. When the wire cutting wire 4 of different diameters needs to be replaced in different cutting environments, the corresponding mounting hole can be removed and a different wire row wheel 7eb can be replaced, thereby ensuring that the wire cutting wire 4 can be effectively tensioned on the wire row wheel 7eb.

[0092] Preferably, the wire arrangement wheel 7eb includes a rotating shaft 7eba and a wheel 7ebb;

[0093] The rotating shaft 7eba is fixed to the mounting block 7ea through a bearing, and the rotating shaft 7eba protrudes from the mounting block 7ea; the wheel 7ebb is rotatably arranged on the protruding part of the rotating shaft 7eba, and the wheel 7ebb is provided with an annular groove 7ebc along the outer periphery, the width of the groove 7ebc is greater than the diameter of the wire cutting wire 4, and the wire cutting wire 4 is wound in the groove 7ebc.

[0094] Since the wire cutting wire 4 needs to be replaced frequently, and in order to prevent the wire cutting wire 4 from detaching from the wheel 7ebb, it is usually wrapped around the wheel 7ebb once and then led out of the wheel 7ebb. In order to be able to install the wire cutting wire 4 more conveniently, in the utility model, a groove 7ebc is provided on the outer circumferential surface of the wheel 7ebb, and the width of the groove 7ebc matches the diameter of the wire cutting wire 4. When replacing or installing the wire cutting wire 4, it is only necessary to place the wire cutting wire 4 into the groove 7ebc. The left and right side walls of the groove 7ebc will limit the left and right sides of the wire cutting wire 4 to prevent the wire cutting wire 4 from detaching. At this time, there is no need to wrap the wire cutting wire 4 around the wheel 7ebb, which greatly improves the efficiency of the wire cutting wire 4 when replacing or installing.

[0095] Preferably, a connecting arm 8 extending forward is provided at the top of the support column 1, a mounting plate 9 is provided at the front end of the connecting arm 8, and the front wire winding device 2 and the wire cutting head 6 are arranged on the mounting plate 9; a cutting wire drum 10 is provided between the front wire winding device 2 and the wire cutting head 6, and the wire cutting wire 4 passes through the wire cutting head 6, passes through the cutting wire drum 10 and the movable guide device 7, and is fixed to the front wire winding device 2.

[0096] By adopting the above structure, the horizontal distance between the support column 1 and the wire cutting head 6 can be extended, so that the operating space below the wire cutting head 6 is larger, which is convenient for the wire cutting device to perform wire cutting on large workpieces to be processed.

[0097] The cutting wire drum 10 plays a guiding role, so that the wire cutting wire 4 can be wound around the front wire storage drum 2a, wherein the structure of the cutting wire drum 10 is consistent with the structure of the wire arranging component 7e.

[0098] Preferably, the front wire winding device 2 comprises a front wire storage drum 2a and a front wire storage drum driving assembly 2b;
