Description

Technical Field

[0001] This invention relates to the field of packaging strap processing technology, specifically a printing device for producing composite plastic strapping. Background Technology

[0002] Plastic strapping is also known as plastic packing strap. Packaging strapping (strapping) is made primarily of polyethylene, polypropylene resin, and cold-rolled steel strip. Some are also made of nylon and polyester. It is produced by extrusion and unidirectional stretching, followed by heat treatment and bluing. During the processing of strapping, printing equipment is used to print parameters and logos.

[0003] However, existing processing equipment has the following shortcomings:

[0004] In existing equipment, such as CN214918817U, this utility model discloses a printing device for the production of composite plastic strapping and packaging straps, relating to the field of strapping and packaging strap production technology. To address the problem that existing printing devices for composite plastic strapping and packaging straps are generally located in factory workshops, making the surface of the strapping straps easily contaminated with dust, affecting subsequent laser printing, the printing device comprises a printing drive end mounted on the upper part of the main body of the strapping strap printing mechanism, a printing end mounted on the lower surface of the printing drive end, a suction fan mounted at one end inside the printing drive end, a dust filter bag layer mounted below the suction fan, a suction mesh port mounted below the dust filter bag layer, an exhaust port mounted on the upper surface of the suction fan, a printing support frame mounted on the rear end face of the printing drive end, and two sets of printing support frames mounted thereon. An electric vertical guide rail assembly is mounted on the outer wall of the front face of the printing support frame, and a take-up roller observer is mounted at the other end inside the printing drive end. This solves the problem that existing printing devices for composite plastic strapping and packaging straps are generally located in factory workshops, making the surface of the strapping straps easily contaminated with dust, affecting subsequent laser printing.

[0005] In their daily work, the inventors discovered that when laser printing is performed on cable ties, the cable ties are prone to swinging up, down, left, and right, affecting the printing effect. At the same time, the existing technology uses displacement detectors to detect cable tie deviation, which is costly and difficult to maintain.

[0006] Therefore, we propose a printing device for the production of composite plastic strapping to solve the problems mentioned above. Summary of the Invention

[0007] The purpose of this invention is to provide a printing device for producing composite plastic strapping. The strapping is passed between an elastic rope and a support shaft, which can limit the up-and-down swing of the suspended part of the strapping during transmission. When the motor is turned on, the motor drives the bidirectional screw to rotate. The bidirectional screw drives two sets of moving frames to move in the stabilizing rod. The two sets of limiting rings can restrict the strapping to the left and right, thereby solving the problems mentioned in the background art.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a printing device for producing composite plastic strapping, comprising a support frame, wherein an upper feeding shaft and an lower feeding shaft are rotatably connected to the surface of the support frame, a laser printing head is provided on the surface of the support frame, and an auxiliary device is provided on the surface of the support frame, wherein the auxiliary device comprises four hollow seats, each of which is fixedly connected to two opposite sides of the support frame, a support shaft is rotatably connected to the inner wall of two hollow seats, and an elastic rope is fixedly connected to a corresponding point of the two hollow seats. Through the cooperation of the hollow seats and the support shafts, the support shafts can support the strapping during transport. At the same time, when the support shafts provide support, the elastic ropes can prevent the strapping from swinging up and down during transport, thus avoiding any impact on the printing process.

[0009] Preferably, the inner wall of the bracket is fixedly connected to two stabilizing rods, and the surfaces of the two stabilizing rods are slidably connected to two movable frames. The surfaces of the movable frames are fixedly connected to limiting components, which are sleeved and connected to the support shaft. The surface of the bracket is fixedly connected to two hollow blocks, and the inner walls of the hollow blocks are rotatably connected to bidirectional screws. The surfaces of the two movable frames are provided with screw holes, and the bidirectional screws are threaded to the inner walls of the screw holes. By rotating the bidirectional screws, the movable frames and limiting components can be moved. The limiting components can limit the binding straps supported on the support shaft, reducing the possibility of printing errors caused by the binding straps being moved.

[0010] Preferably, the limiting member is composed of a fixing strip and a limiting ring. The limiting ring has a limiting hole on its surface, through which the elastic rope passes. By setting the limiting hole on the surface of the limiting member, it is convenient for the elastic rope to be adjusted in the upper and lower ranges.

[0011] Preferably, a motor is fixedly connected to one side surface of the bracket, and the output end of the motor is connected to the bidirectional screw via a belt. By setting the motor, it is easy to control the rotation of the bidirectional screw and facilitate automatic adjustment.

[0012] Preferably, a cleaning device is provided on the side of the bracket near the feeding shaft. The cleaning device includes two hollow sleeves, which are fixedly connected to the surface of the bracket. A sliding rod is slidably connected to the inner wall of the hollow sleeve. A moving block is fixedly connected to the upper end of the two sliding rods. A cleaning brush is provided on one side of the moving block. By providing the cleaning brush, the surface of the strapping can be cleaned, reducing the impact of stains and dust on the printing effect.

[0013] Preferably, a first spring is fixedly connected to the side of the slide rod corresponding to the inner wall of the hollow sleeve. There are two first springs. By setting the first springs, it is convenient to apply downward pressure to the slide rod and the hollow sleeve, so that the cleaning brush can fit into the strapping and improve the cleaning effect.

[0014] Preferably, a handle is fixedly connected to the upper surface of the movable block. The longitudinal section of the handle is U-shaped. By setting the U-shaped handle, it is easy to pull the movable block to move and to make it convenient for adjustment and use.

[0015] Preferably, the surface of the bracket is provided with a collection device, which includes an exhaust fan. The exhaust fan is fixedly connected to the surface of the bracket. A suction tube is fixedly connected to the input end of the exhaust fan. A suction head is provided on the surface of the movable block. One end of the suction tube is fixedly connected to the surface of the suction head. A hollow ring is fixedly connected to the output end of the exhaust fan. A collection box is provided on the side of the bracket near the exhaust fan. A plug ring is fixedly connected to one end of the collection box. The plug ring is inserted into the inner wall of the hollow ring. By setting the exhaust fan in conjunction with the suction tube and suction head, dust generated during cleaning can be sucked into the collection box for collection.

[0016] Preferably, the hollow ring has a connecting hole on its surface, and a positioning rod is slidably connected to the inner wall of the connecting hole. The insertion ring has a positioning groove on its surface, and the positioning rod is inserted into the positioning groove. By cooperating with the positioning groove, the insertion ring can be stably confined in the hollow ring, which facilitates collection and processing.

[0017] Preferably, a second spring is sleeved on the surface of the positioning rod, and the two ends of the second spring are fixedly connected to the surfaces of the positioning rod and the hollow ring, respectively. By setting the second spring, it is convenient to control the positioning rod to reset and improve the binding effect of the positioning rod.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. When using the equipment of this invention, the strapping is placed on the feeding shaft and moved to the unloading shaft, thereby driving the strapping for transmission. During transmission, the laser printing head prints on the strapping. By setting an auxiliary device, when the equipment is needed, the strapping is passed between the elastic rope and the support shaft, which can limit the up-and-down swing of the strapping during transmission. The motor is turned on, and the motor drives the bidirectional screw to rotate. The bidirectional screw drives two sets of moving frames to move in the stabilizing rod. The two sets of limiting rings can limit the left and right movement of the strapping. By setting an auxiliary device, it is easier to assist the strapping in printing. This can effectively reduce the phenomenon that the strapping is prone to swinging up and down and left and right when laser printing, which affects the printing effect. It also reduces the high cost and subsequent maintenance difficulty of using displacement detectors to detect strapping deviation in the existing technology, thereby improving the overall stability of the equipment.

[0020] 2. This invention incorporates a cleaning device. When the equipment is needed, the moving block and cleaning brush are lifted by the handle. As the strapping strap passes through from the bottom, the handle is released, the first spring releases its elasticity, and the moving block and cleaning brush are pulled downwards, causing the cleaning brush to adhere to the surface of the strapping strap. During strapping strap transmission, the cleaning brush cleans and wipes its surface. By incorporating this cleaning device, cleaning of the strapping strap during printing is facilitated. This effectively reduces the likelihood of the strapping strap surface easily accumulating stains and dust during the printing process, and addresses the issue of some stains remaining unremoved when using a blower, thus reducing the impact of stains on subsequent printing quality and improving the overall usability of the equipment.

[0021] 3. This invention incorporates a collection device. When the equipment is needed, turning on the exhaust fan allows the suction head and suction tube to collect the cleaned dust and stains into the collection box. After collection, pulling the positioning rod causes the second spring to be stressed, releasing the positioning rod from the positioning groove on the insert ring surface. This allows the insert block to be removed from the hollow ring, enabling the collected dust to be processed. By incorporating the collection device, the dust generated during cleaning is easily collected, effectively reducing the likelihood of dust scattering onto the machine or becoming airborne during cleaning, thus improving the overall practicality of the equipment.

Detailed Implementation

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Please see Figure 1-8 As shown, the present invention provides a technical solution: a printing device for producing composite plastic strapping, including a support 1, with an upper feeding shaft 2 and an lower feeding shaft 3 rotatably connected to the surface of the support 1, and a laser printing head 4 provided on the surface of the support 1.

[0033] according to Figure 2-3 As shown, specifically, the surface of the support 1 is provided with an auxiliary device 5, which includes four hollow seats 55. The four hollow seats 55 are fixedly connected to the two side surfaces of the support 1 in pairs. The inner walls of two hollow seats 55 are rotatably connected to a support shaft 56. An elastic rope 57 is fixedly connected to a corresponding point of the two hollow seats 55. Through the cooperation of the hollow seats 55 and the support shaft 56, the support shaft 56 can support the strapping during transportation. At the same time, when the support shaft 56 supports, it cooperates with the elastic rope 57 to prevent the strapping from swinging up and down during transportation, thus affecting the printing.

[0034] according to Figure 2-4As shown, specifically, two stabilizing rods 51 are fixedly connected to the inner wall of the support 1. Two movable frames 52 are slidably connected to the surfaces of the two stabilizing rods 51. Limiting components 58 are fixedly connected to the surfaces of the movable frames 52. The limiting components 58 are sleeved and connected to the support shaft 56. Two hollow blocks are fixedly connected to the surface of the support 1. A bidirectional screw 54 is rotatably connected to the inner wall of the hollow blocks. Screw holes are opened on the surfaces of the two movable frames 52. The bidirectional screw 54 is threadedly connected to the inner wall of the screw hole. By rotating the bidirectional screw 54, the movable frames 52 and the limiting components 58 can be moved. The limiting components 58 can limit the binding strap supported on the support shaft 56, reducing the possibility of the binding strap being moved and causing printing errors.

[0035] according to Figure 4 As shown, specifically, the limiting member 58 is composed of a fixing strip and a limiting ring. The limiting ring in the limiting member 58 has a limiting hole 59 on its surface, through which the elastic rope 57 passes. By setting the limiting hole 59 on the surface of the limiting member 58, it is convenient for the elastic rope 57 to be adjusted in the upper and lower ranges.

[0036] according to Figure 2 As shown, specifically, a motor 53 is fixedly connected to one side surface of the bracket 1. The output end of the motor 53 is connected to the bidirectional screw 54 via a belt. By setting the motor 53, it is easy to control the rotation of the bidirectional screw 54 and facilitate automatic adjustment.

[0037] according to Figure 5-6 As shown, specifically, a cleaning device 6 is provided on the side of the support 1 near the feeding shaft 2. The cleaning device 6 includes two hollow sleeves 61. The two hollow sleeves 61 are fixedly connected to the surface of the support 1. A sliding rod 65 is slidably connected to the inner wall of the hollow sleeve 61. A moving block 62 is fixedly connected to the upper end of the two sliding rods 65. A cleaning brush 64 is provided on one side of the moving block 62. By setting the cleaning brush 64, the surface of the strapping can be cleaned, reducing the impact of stains and dust on the printing effect.

[0038] according to Figure 6 As shown, specifically, a first spring 66 is fixedly connected to the side of the slide rod 65 corresponding to the inner wall of the hollow sleeve 61. There are two first springs 66. By setting the first springs 66, it is convenient to apply downward pressure to the slide rod 65 and the hollow sleeve 61, so that the cleaning brush 64 fits against the strapping and improves the cleaning effect.

[0039] according to Figure 5 As shown, specifically, a handle 63 is fixedly connected to the upper surface of the movable block 62. The longitudinal section of the handle 63 is U-shaped. By setting the U-shaped handle 63, it is easy to pull the movable block 62 to move it, and it is convenient to adjust and use it.

[0040] according to Figure 1-2As shown in Figure 7, specifically, a collection device 7 is provided on the surface of the support 1. The collection device 7 includes an exhaust fan 71, which is fixedly connected to the surface of the support 1. A suction tube 74 is fixedly connected to the input end of the exhaust fan 71. A suction head 73 is provided on the surface of the moving block 62. One end of the suction tube 74 is fixedly connected to the surface of the suction head 73. A hollow ring 75 is fixedly connected to the output end of the exhaust fan 71. A collection box 72 is provided on the side of the support 1 near the exhaust fan 71. A plug ring 76 is fixedly connected to one end of the collection box 72. The plug ring 76 is inserted into the inner wall of the hollow ring 75. By setting the exhaust fan 71 in conjunction with the suction tube 74 and the suction head 73, the dust generated during cleaning can be sucked into the collection box 72 for collection.

[0041] according to Figure 8 As shown, specifically, the surface of the hollow ring 75 has a connecting hole, and the inner wall of the connecting hole is slidably connected to a positioning rod 77. The surface of the insertion ring 76 has a positioning groove, and the positioning rod 77 is inserted into the positioning groove. By cooperating with the positioning groove, the insertion ring 76 can be stably restricted in the hollow ring 75, which is convenient for collection and processing.

[0042] according to Figure 8 As shown, specifically, a second spring 78 is sleeved on the surface of the positioning rod 77. The two ends of the second spring 78 are fixedly connected to the surfaces of the positioning rod 77 and the hollow ring 75, respectively. By setting the second spring 78, it is easy to control the positioning rod 77 to reset and improve the binding effect of the positioning rod 77.

[0043] The overall effect of the mechanism is as follows: by placing the strapping on the feeding shaft 2 and moving it on the unloading shaft 3, the strapping is driven to move. During the movement, the laser printing head 4 prints on the strapping. By setting an auxiliary device 5, when the equipment needs to be used, the strapping is passed between the elastic rope 57 and the support shaft 56, which can limit the up-and-down swing of the strapping during the movement. The motor 53 is turned on, and the motor 53 drives the bidirectional screw 54 to rotate. The bidirectional screw 54 drives the two sets of moving frames 52 to move in the stabilizing rod 51. The two sets of limiting rings can limit the left and right movement of the strapping. By setting the auxiliary device 5, it is easier to assist the strapping in printing. This can effectively reduce the phenomenon that the strapping is prone to swinging up and down and left and right when laser printing, which affects the printing effect. It also reduces the high cost and subsequent maintenance difficulty of using displacement detectors to detect strapping deviation in existing technologies, thereby improving the overall stability of the equipment.

[0044] By setting up the cleaning device 6, when the equipment needs to be used, the moving block 62 and the cleaning brush 64 are lifted by the handle 63. When the strapping strap passes through from the bottom, the handle 63 is released, the first spring 66 releases its elasticity, and the moving block 62 and the cleaning brush 64 are pulled down, so that the cleaning brush 64 is in contact with the surface of the strapping strap. When the strapping strap is being transported, the cleaning brush 64 cleans and wipes its surface. By setting up the cleaning device 6, it is convenient to clean the strapping strap during printing. This can effectively reduce the phenomenon that the surface of the strapping strap is easily contaminated with some stains and dust during the printing process, and that the cleaning effect of using a blower is poor and some adsorbed stains cannot be cleaned. This reduces the impact of stains on the subsequent printing quality, thereby improving the overall usability of the equipment.

[0045] By setting up the collection device 7, when the equipment needs to be used, the exhaust fan 71 is turned on, allowing the suction head 73 to work with the suction tube 74 to suck up the cleaned dust and stains into the collection box 72. After collection, the positioning rod 77 is pulled, the second spring 78 is stressed, and the positioning rod 77 is no longer restrained by the positioning groove on the surface of the insertion ring 76. The insertion block is then removed from the hollow ring 75, and the collected dust can be processed. By setting up the collection device 7, it is easy to collect the dust generated during cleaning, which can effectively reduce the phenomenon that dust generated during cleaning is easy to fall onto the machine or float around, reduce the situation of poor cleaning effect, and thus improve the overall practicality of the equipment.
