Description

Technical Field

[0001] The invention relates to the technical field of quick assembly and disassembly of moulds, in particular to quick assembly and disassembly of moulds equipment specially used for pattern machines. Background Art

[0002] Pattern machine is a sewing equipment widely used in textile, clothing, leather and other industries. It can sew various patterns and designs on various materials. Pattern machine needs to use molds to sew different patterns and designs. When sewing, the cloth should be placed between the molds. The molds should be loaded and unloaded every time sewing. Therefore, the loading and unloading of the molds is a very important link, which directly affects the production efficiency and product quality of the pattern machine. The traditional method of loading and unloading the molds of pattern machines is mainly to manually disassemble and install the molds. This method is not only inefficient, but also prone to problems such as loose mold installation and mold damage, thereby affecting the production efficiency and product quality of the pattern machine. In order to solve the problems existing in the traditional method of loading and unloading the molds of pattern machines and improve the production efficiency and product quality of pattern machines, a fast loading and unloading mold equipment dedicated to pattern machines came into being. This equipment adopts advanced automation technology and mechanical structure, which can realize the fast loading and unloading of the molds of pattern machines, and improve the production efficiency and product quality of pattern machines.

[0003] When installing the mold, it is necessary to place the mold on the workbench of the pattern machine, and the quick loading and unloading mold equipment fixes one side of the mold on the workbench through a clamp. The existing mold is an openable and closable iron plate with a pattern groove on the iron plate. The openable and closable mold clamps the cloth between the iron plates. Due to the different thicknesses of different cloths, when the mold with thick cloth is fixed on one side by the equipment, the cover plate on the other side of the mold will warp up, resulting in a loose closure of the mold, thereby affecting the accuracy of cloth processing and the integrity of the pattern. The warping of the mold cover causes the cloth to have problems such as wrinkles and deformation during processing, affecting the quality of the final product.

[0004] Secondly, the installation of the mold needs to be accurately placed according to the position of the positioning column. However, the positioning range of the existing positioning column and the mold size are relatively single, which cannot meet the diverse production tasks and reduces the flexibility of production. The thread ends at the sewing head of the pattern machine are generally dragged out to ensure that the thread ends will not fall off easily during the sewing process, thereby ensuring the firmness and quality of the sewing. However, when the mold is installed, the thread ends will be pressed under the mold. The thread ends are pressed, resulting in uneven sewing lines, affecting the firmness and quality of the sewing. The thread ends are more likely to break under pressure, resulting in sewing interruptions.

[0005] Therefore, the present invention proposes a quick-loading and unloading mold device specifically for a pattern machine to improve the shortcomings of traditional technology. It can simultaneously fix both sides of the mold to prevent one side from warping due to thicker fabric, ensure that the mold remains stable during processing, and adjust the position of the positioning column to adapt to the size of different molds. Summary of the invention

[0006] In view of the deficiencies of the prior art, the present invention provides a quick-loading and unloading mold device specifically for a pattern machine, which solves the problems raised in the above-mentioned background technology.

[0007] To achieve the above objectives, the present invention is implemented through the following technical solutions: a quick-loading and unloading mold device specially used for a pattern machine, comprising a workbench, a pattern sewing device is fixedly connected to the upper surface of the workbench, a pattern mold is movably connected to the upper surface of the workbench, a sewing thread head is movably connected to the outer surface of the pattern sewing device, a fixing component for fixing both ends of the pattern mold is arranged on the outside of the workbench, and an auxiliary component for improving production flexibility is arranged on the outside of the workbench.

[0008] Preferably, the fixing assembly includes a connecting plate, both ends of which are rotatably connected to a first cylinder, the outer surface of the first cylinder is movably connected to a fixed cylinder, the outer surface of the fixed cylinder is provided with a threaded groove, the interior of the threaded groove is slidably connected to a second cylinder, one end of the second cylinder located inside the fixed cylinder is fixedly connected to the outer surface of the first cylinder, and the top end of the first cylinder is fixedly connected to a fixing rod.

[0009] Preferably, the first cylinder passes through and is movably connected to the interior of the workbench.

[0010] Preferably, the bottom of the fixed cylinder is fixedly connected to the upper surface of the workbench.

[0011] Preferably, the auxiliary component includes a square groove, which is opened on the upper surface of the workbench, and a two-way screw rod is rotatably connected to the interior of the square groove, and the outer surface of the two-way screw rod is threadedly connected to two positioning columns, and one end of the two-way screw rod outside the square groove is fixedly connected to an auxiliary gear, and the outer surface of the auxiliary gear is meshingly connected to an auxiliary rack, and both ends of the auxiliary rack are fixedly connected to fixed columns, and the outer surface of the fixed column is slidably connected to an auxiliary plate, and the outer surface of the auxiliary plate is fixedly connected to a single gear tooth, a return spring is fixedly connected between the bottom of the auxiliary plate and the fixed column, the outer surface of the auxiliary rack is fixedly connected to an auxiliary rod, and the bottom of the auxiliary rod is fixedly connected to a blocking plate.

[0012] Preferably, the auxiliary rod penetrates and slides inside the workbench.

[0013] Preferably, the single gear tooth is meshingly connected to an outer surface of the auxiliary gear.

[0014] The quick-loading and unloading mold equipment specially used for the pattern machine provided by the present invention has the following beneficial effects:

[0015] 1. By installing fixing rods at both ends of the pattern mold, both sides of the pattern mold can be fixed at the same time to prevent one side from warping due to thick fabric. The existence of the fixing rod helps to maintain the precise alignment between the pattern mold and the fabric, so that the pattern mold is tightly closed, ensuring that the size and shape of each pattern sewing are consistent. By moving the connecting plate and driving the two first cylinders to move synchronously at the same time, the consistency of the process can be improved, ensuring that the pattern mold remains stable during use, and reducing the warping problem caused by only fixing one end of the pattern mold due to different fabric thicknesses. Through the setting of the threaded groove and the second cylinder, rotary pressing is achieved. When it is not fixed, the space of the pattern mold is first cleared, and the pattern mold is put in and then pressed, which can improve the flexibility and utilization of the working area. Compared with the existing vertical pressing, this method will not limit the operating space. The operator can more easily place, align and fix the pattern mold, reducing the demand for vertical space, making the operation more flexible and convenient.

[0016] 2. Through the coordinated use of the bidirectional screw and the positioning column, the bidirectional screw can be rotated to adjust the positions of the two positioning columns. The adjustment of the positioning column can adapt to different positioning ranges and mold sizes, meet diversified production tasks, and improve production flexibility. Through the coordinated use of the bidirectional screw, the positioning column, the auxiliary rack and the auxiliary rod, the bidirectional screw adjustment is achieved while the auxiliary rod moves upward. Before the pattern mold is placed on the workbench, the sewing thread head is raised to avoid the thread head being pressed under the pattern mold during installation, and to prevent the sewing thread from being pressed and causing the sewing line to be unsmooth, thereby improving the firmness and quality of the suture, and avoiding the thread head being broken by pressure and causing sewing interruption. When installing the pattern mold, the sewing thread head is raised to reduce the downtime caused by the thread head being pressed under the pattern mold, thereby improving the overall work efficiency.

[0017] 3. Through the coordinated use of the fixed column, the auxiliary plate, the single gear tooth and the reset spring, the auxiliary gear is rotated to drive the bidirectional screw rod to adjust the positioning column within a range that is not limited by the auxiliary rack. This means that the rotation of the auxiliary gear can be independently controlled without affecting the position of the positioning column. This independent control provides greater flexibility for operation. When the auxiliary gear rotates to a single gear tooth, it stops driving the auxiliary rack to move, and the auxiliary gear can continue to rotate without being affected by the auxiliary rack. This design can save the cost of a drive device to control the up and down movement of the auxiliary rod. This linkage design reduces the number and complexity of parts, making the entire structure simpler and more compact. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] refer to Figures 1 to 9 As shown, a preferred embodiment of the present invention will be described in detail below:

[0033] A quick-loading and unloading mold device specially used for a pattern machine comprises a workbench 1, a pattern sewing device 2 is fixedly connected to the upper surface of the workbench 1, a pattern mold 3 is movably connected to the upper surface of the workbench 1, limiting grooves are arranged on both sides of the pattern mold 3 for placing and clamping a positioning column 63, a sewing thread head 4 is movably connected to the outer surface of the pattern sewing device 2, a fixing component 5 for fixing the two ends of the pattern mold 3 is arranged outside the workbench 1, and an auxiliary component 6 for improving production flexibility is arranged outside the workbench 1.

[0034] The fixing assembly 5 includes a connecting plate 51, which is driven and installed on an external driving device. Both ends of the connecting plate 51 are rotatably connected to a first cylinder 52, and the outer surface of the first cylinder 52 is movably connected to a fixed cylinder 53. A threaded groove 54 is provided on the outer surface of the fixed cylinder 53, and a second cylinder 55 is slidably connected inside the threaded groove 54. One end of the second cylinder 55 located inside the fixed cylinder 53 is fixedly connected to the outer surface of the first cylinder 52, and a fixing rod 56 is fixedly connected to the top of the first cylinder 52. The first cylinder 52 passes through and is movably connected to the inside of the workbench 1, and the bottom of the fixed cylinder 53 is fixedly connected to the upper surface of the workbench 1. By installing fixing rods 56 at both ends of the pattern mold 3, both sides of the pattern mold 3 can be fixed at the same time to prevent one side from warping due to thicker fabric. The existence of the fixing rod 56 helps The precise alignment between the pattern mold 3 and the fabric is maintained, so that the pattern mold 3 is tightly closed, and the size and shape of each pattern sewing are ensured to be consistent. The connection plate 51 is moved and the two first cylinders 52 are driven to move synchronously at the same time, so that the consistency of the process can be improved, and the pattern mold 3 can be ensured to remain stable during use, and the problem of warping caused by only fixing one end of the pattern mold 3 due to different thicknesses of the fabric is reduced. The threaded groove 54 and the second cylinder 55 are set to achieve rotational pressing. When it is not fixed, the space of the pattern mold 3 is first cleared, and the pattern mold 3 is put in and then pressed, which can improve the flexibility and utilization of the working area. Compared with the existing vertical pressing, this method does not limit the operating space. The operator can more easily place, align and fix the pattern mold 3, reducing the demand for vertical space and making the operation more flexible and convenient.

[0035] The auxiliary component 6 includes a square groove 61, which is provided on the upper surface of the workbench 1. A bidirectional screw rod 62 is rotatably connected to the inside of the square groove 61. A symmetrical spiral groove is provided on the outer surface of the bidirectional screw rod 62. Positioning columns 63 are respectively slid inside the two spiral grooves. The rotation of the bidirectional screw rod 62 can simultaneously drive the two positioning columns 63 to move closer to and away from each other. The outer surface of the bidirectional screw rod 62 is threadedly connected to two positioning columns 63. Through the coordinated use of the bidirectional screw rod 62 and the positioning columns 63, the bidirectional screw rod 62 can rotate to adjust the positions of the two positioning columns 63. The adjustment of the positioning columns 63 can adapt to different positioning ranges and mold sizes, meet diverse production tasks, and improve production flexibility.

[0036] One end of the bidirectional lead screw 62 outside the square groove 61 is fixedly connected to an auxiliary gear 64, and the auxiliary gear 64 is driven and installed on an external driving device. The number of teeth of the auxiliary gear 64 is twice the number of teeth of the auxiliary rack 65, so that the auxiliary gear 64 can drive the auxiliary rack 65 to move to the bottom end by rotating half a circle. The outer surface of the auxiliary gear 64 is meshingly connected with the auxiliary rack 65, and both ends of the auxiliary rack 65 are fixedly connected with fixed columns 66, and the outer surface of the fixed column 66 is slidably connected with an auxiliary plate 67, and the outer surface of the auxiliary plate 67 is fixedly connected with a single gear tooth 68, and a return spring 69 is fixedly connected between the bottom of the auxiliary plate 67 and the fixed column 66. The outer surface of the auxiliary rack 65 is fixedly connected with an auxiliary rod 610, By using the fixed column 66, the auxiliary plate 67, the single gear tooth 68 and the return spring 69 in coordination, the auxiliary gear 64 can rotate to drive the bidirectional screw rod 62 to adjust the positioning column 63 within a range that is not limited by the auxiliary rack 65. This means that the rotation of the auxiliary gear 64 can be independently controlled without affecting the position of the positioning column 63. This independent control provides greater flexibility for operation. When the auxiliary gear 64 rotates to the single gear tooth 68, it stops driving the auxiliary rack 65 to move, while the auxiliary gear 64 can continue to rotate without being affected by the auxiliary rack 65. This design can save the cost of a drive device to control the up and down movement of the auxiliary rod 610. This linkage design reduces the number and complexity of parts, making the entire structure simpler and more compact.

[0037] The auxiliary rod 610 is used to prevent the auxiliary gear 64 from rotating so that the auxiliary rack 65 continues to move upward. The size of the blocking plate 611 is larger than the size of the bottom end of the auxiliary rod 610. The blocking force of the blocking plate 611 can make the auxiliary gear 64 rotate and squeeze the reset spring 69. The sewing thread head 4 can pass through the inside of the auxiliary rod 610. The bottom of the auxiliary rod 610 is fixedly connected with the blocking plate 611. The bottom end of the auxiliary rod 610 penetrates and slides inside the workbench 1. The single gear tooth 68 is meshed and connected with the outer surface of the auxiliary gear 64. Through the bidirectional screw rod 62, the positioning column 63, and the auxiliary rack 65 and the auxiliary rod 610 are used in conjunction with each other to achieve the adjustment of the bidirectional screw rod 62 while the auxiliary rod 610 moves upward to lift the sewing thread end 4 before the pattern mold 3 is placed on the workbench 1, so as to avoid the thread end being pressed under the pattern mold 3 during installation, and to prevent the sewing thread end 4 from being pressed, resulting in uneven sewing, thereby improving the firmness and quality of suturing, and avoiding the thread end being broken by pressure, resulting in sewing interruption. When installing the pattern mold 3, the sewing thread end 4 is lifted up, which can reduce the downtime caused by the thread end being pressed under the pattern mold 3, thereby improving the overall work efficiency.

[0038] The following is the entire working process and working principle of the above embodiment:

[0039] In the initial state, the two positioning posts 63 are located at both ends of the bidirectional screw rod 62, the return spring 69 is not compressed, the top position of the auxiliary rack 65 is engaged with the auxiliary gear 64, and the sewing thread head 4 passes through the interior of the auxiliary rod 610.

[0040] First, before the pattern sewing device 2 works, the operator adjusts the position of the positioning column 63, the operator starts the driving device, the driving device controls the auxiliary gear 64 to rotate, the rotation of the auxiliary gear 64 drives the bidirectional screw rod 62 to rotate, and the rotation of the bidirectional screw rod 62 simultaneously drives the two positioning columns 63 to move closer to each other to the required position. Through the coordinated use of the bidirectional screw rod 62 and the positioning column 63, the bidirectional screw rod 62 can rotate to adjust the position of the two positioning columns 63. The adjustment of the positioning column 63 can adapt to different positioning ranges and mold sizes, meet diversified production tasks, and improve production flexibility.

[0041] At the same time, the rotation of the auxiliary gear 64 drives the auxiliary rack 65 meshing with it to move upward. Since the number of teeth of the auxiliary gear 64 is twice that of the auxiliary rack 65, the auxiliary gear 64 can drive the auxiliary rack 65 to move upward by rotating half a circle. This arrangement is to avoid the situation where the auxiliary rack 65 has not moved up as a whole after the positioning column 63 is adjusted. When the auxiliary gear 64 rotates to the bottom end of the auxiliary rack 65 and touches the single gear tooth 68, the rotational force of the auxiliary gear 64 will cause the gear teeth of the auxiliary gear 64 to continuously squeeze the single gear tooth 68 and drive it to move. The continuous movement of the single gear tooth 68 drives the auxiliary plate 67 to slide on the outer surface of the fixed column 66. During the sliding process of the auxiliary plate 67, the reset spring 69 is continuously squeezed. The elastic force of the reset spring 69 and the rotation of the auxiliary gear 64 cause the single gear tooth 68 to move. The gear teeth 68 continuously drive the auxiliary plate 67 to slide up and down on the surface of the fixed column 66. Through the coordinated use of the fixed column 66, the auxiliary plate 67, the single gear teeth 68 and the reset spring 69, the auxiliary gear 64 rotates to drive the bidirectional screw rod 62 to adjust the positioning column 63. The range is not limited by the auxiliary rack 65, which means that the rotation of the auxiliary gear 64 can be independently controlled without affecting the position of the positioning column 63. This independent control provides greater flexibility for operation. When the auxiliary gear 64 rotates to the single gear tooth 68, it stops driving the auxiliary rack 65 to move, and the auxiliary gear 64 can continue to rotate without being affected by the auxiliary rack 65. This design can save the cost of a drive device to control the up and down movement of the auxiliary rod 610. This linkage design reduces the number and complexity of parts, making the entire structure simpler and more compact.

[0042] At the same time, when the auxiliary rack 65 moves upward, it will drive the auxiliary rod 610 to move upward, and the bottom end of the auxiliary rod 610 slides inside the workbench 1. The auxiliary rod 610 moves upward and drives the sewing thread head 4 to move upward, so that the sewing thread head 4 does not contact the surface of the workbench 1. Through the coordinated use of the bidirectional screw rod 62, the positioning column 63, the auxiliary rack 65 and the auxiliary rod 610, the bidirectional screw rod 62 is adjusted while the auxiliary rod 610 moves upward. Before the pattern mold 3 is placed on the workbench 1, the sewing thread head 4 is lifted, so that the pattern mold 3 is prevented from pressing the thread head under the pattern mold 3 during installation, and the sewing thread is prevented from being pressed. The firmness and quality of the suturing are improved, and the thread head is prevented from being broken due to pressure, resulting in sewing interruption. When the pattern mold 3 is installed, the sewing thread head 4 is lifted to reduce the downtime caused by the thread head being pressed under the pattern mold 3, thereby improving the overall work efficiency.

[0043] After the positioning column 63 is adjusted and the sewing thread head 4 is lifted, the operator places the pattern mold 3 on the workbench 1, and the limiting grooves on both sides of the pattern mold 3 put the two positioning columns 63 into the pattern mold 3 to align the pattern mold 3. The operator starts the driving device, and the driving device controls the connecting plate 51 to move downward. The connecting plate 51 moves downward to drive the two first cylinders 52 to move downward. The first cylinder 52 moves downward to drive the second cylinder 55 and the fixing rod 56 to move downward. The second cylinder 55 slides inside the thread groove 54. The second cylinder 55 slides inside the thread groove 54 to make the first cylinder 52 rotate downward inside the workbench 1. The first cylinder 52 rotates downward to drive the fixing rod 56 to rotate downward to fix the two ends of the pattern mold 3. By installing the fixing rods 56 at both ends of the pattern mold 3, both sides of the pattern mold 3 can be fixed at the same time to prevent one side from warping due to thicker fabric. The existence of the fixing rod 56 helps to maintain the precise alignment between the pattern mold 3 and the cloth, so that the pattern mold 3 is tightly closed, ensuring that the size and shape of each pattern sewing are consistent. By moving the connecting plate 51 and driving the two first cylinders 52 to move synchronously at the same time, the consistency of the process can be improved, ensuring that the pattern mold 3 remains stable during use, and reducing the problem of warping caused by only fixing one end of the pattern mold 3 due to different thicknesses of the cloth. The setting of the threaded groove 54 and the second cylinder 55 can achieve rotational pressing. When it is not fixed, the space of the pattern mold 3 is first cleared, and the pattern mold 3 is put in and then pressed, which can improve the flexibility and utilization of the working area. Compared with the existing vertical pressing, this method does not limit the operating space. The operator can more easily place, align and fix the pattern mold 3, reducing the demand for vertical space, making the operation more flexible and convenient.
