Description

Technical Field

[0001] The utility model belongs to the technical field of hanger structures, in particular to a hanger for accumulation type powder spraying coating. Background Art

[0002] Powder coating process refers to a surface treatment process that uses the principle of electrostatic adsorption to spray, fix, and solidify powder coating on the workpiece. The general steps of this process are: workpiece pretreatment, spraying, solidification, and cooling. This process has a wide range of applications and is applicable to plastic parts, metal parts, and wood materials.

[0003] On the other hand, the relatively advanced and efficient powder spray coating process mentioned above is generally online, that is, the workpiece is installed on the conveyor line through a hanger, and then passes through the areas corresponding to the above steps in sequence to achieve the basic powder spray coating effect.

[0004] In addition, the words "accumulation and release" mentioned above refer to the fact that this conveyor line is not a common uniform speed conveyor line. Compared with ordinary conveyor lines, the main functional difference between accumulation and release conveyor lines is that, without stopping the conveyor line, workpieces are allowed to pause and wait at the required position, accumulate multiple times, and then enter each processing area according to the required quantity and speed. Otherwise, the drive motor of the conveyor line needs to be frequently turned on and off to match the conveying speed and the operation time required for each processing area, which will greatly shorten the service life of the drive motor.

[0005] Generally, a power-and-free conveyor line will have a dedicated engaging device between the conveyor line and the hanger, that is, when the engaging relationship is not triggered, the conveyor line can continue to move forward, but the hanger and the workpiece will stop in front of the processing area where it is required to pause.

[0006] Alternatively, a movable connection device is provided between the conveyor line and the hanger, and a blocking device is provided at the entrance of the processing area. The blocking strength of the above blocking device is sufficient to separate the conveyor line and the movable connection device, so that the conveyor line moves forward but the movable connection device does not move. Finally, the blocking device can "put in" the required number of workpieces according to the preset number, interval time and other parameters.

[0007] At this time, the entrance of the processing area will generally stop and wait for multiple workpieces, ultimately ensuring that multiple operating areas with different processing speeds can share a conveyor belt.

[0008] Correspondingly, this requires that the special hangers for the accumulation and release conveyor line have a certain distance separation function to avoid harmful collision and damage between two adjacent workpieces that are accumulated and waiting.

[0009] For example, the Chinese utility model patent with authorization announcement number CN205151519U and authorization announcement date 2016.04.13 discloses a universal hanger for an accumulating hanging chain-type tempering furnace, whose structure includes: a hanger frame and a hanger. The hanger frame is composed of a hinge support, a hanging shaft, a double hook beam, and a lifting ear. The hanger is composed of one or more C-shaped chain links and S-shaped hooks connected in sequence.

[0010] The hanger in this utility model patent has the following advantages: simple structure, simple operation, convenient use, easy management, strong interchangeability and high efficiency.

[0011] However, in actual use, the hanger still has at least the following two shortcomings, which are also the technical problems to be solved by the utility model, namely:

[0012] First, it lacks the necessary conveying direction blocking and limiting structure. When the workpieces on the accumulation and release conveyor line are accumulated and waiting in the waiting area, it is easy for the workpieces to be squeezed and collided with each other, which is particularly obvious for relatively large workpieces.

[0013] Second, its chain link structure can tilt together with the workpiece when picking and placing the workpiece, thereby improving the convenience of the workpiece picking and placing operation. However, this feature that allows tilting is disadvantageous during normal transportation of the workpiece, especially in the waiting area of ​​the accumulation and release conveyor line, which is more likely to damage adjacent workpieces.

[0014] So in summary, there is an urgent need for a new type of hanger with anti-collision function for adjacent workpieces, which is specially used on various types of accumulation and release conveyor lines to ensure that processes such as powder spraying and coating can be carried out safely. Utility Model Content

[0015] The utility model provides a hanging device for accumulation type powder spray coating, which can be arranged on a hook on a chain by means of a sling, a workpiece hook, a main frame unit, a vertical blocking plate unit, a horizontal blocking frame unit, and a combined pipe unit, so that: 1. when the workpieces are accumulated in a waiting area, there is a sufficient and adjustable spacing distance in the conveying direction, so that the workpieces are not easily damaged; 2. the combined pipe unit has a two-speed limiting strength, so that the workpieces have a sufficient tilting amplitude when being taken and placed, and a smaller swing amplitude during transportation, so that the workpieces are still prevented from being damaged.

[0016] The technical solution adopted by the utility model to solve the above-mentioned problems is: a hanger for accumulation-type powder spray coating, the structure of which includes a chain hook, a sling, and a workpiece hook, and also includes a main frame unit with upper and lower ends respectively used to install the chain hook and the sling, a vertical blocking plate unit and a horizontal blocking frame unit respectively arranged at two side positions on the main frame unit and used to increase the distance between two adjacent workpieces, and a combined pipe unit arranged on the main frame unit and used to sleeve the sling.

[0017] A further preferred technical solution is that the main frame unit includes a base plate for installing the sling and the vertical blocking plate unit, two vertical plates respectively arranged at both sides of the base plate and used for installing the chain hook and the horizontal blocking frame unit, and a reinforcing horizontal plate whose two ends are respectively arranged on the two vertical plates and used for installing the vertical blocking plate unit.

[0018] A further preferred technical solution is that the vertical blocking plate unit includes two transverse protruding plates respectively arranged on the bottom plate and the reinforcing transverse plate, and a vertical plate of the transverse blocking frame unit arranged on the two transverse protruding plates and used to block the adjacent hangers.

[0019] A further preferred technical solution is that the transverse blocking frame unit includes two transverse tubes respectively arranged on the two vertical plates, two insertion rods respectively arranged on the two transverse tubes, and a movable transverse plate arranged on the two insertion rods and used to block the vertical blocking plate unit of the adjacent hangers.

[0020] A further preferred technical solution is that the combined pipe unit includes a fixed pipe arranged on the bottom plate and sleeved with the sling, and an extension pipe sleeved on the outer annular surface of the fixed pipe and used to sleeve with the sling by sliding down when the workpiece is moved and transported.

[0021] A further preferred technical solution is that the main frame unit also includes a hanging hole for adding a counterweight arranged on the bottom plate.

[0022] A further preferred technical solution is that the transverse blocking frame unit further includes a plurality of adjustment holes arranged on the transverse tube body, a mounting hole arranged on the insertion rod, and an adjustment rod arranged on the adjustment hole and the mounting hole.

[0023] A further preferred technical solution is that: the transverse blocking frame unit further includes an anti-drop block arranged on the upper end surface of the adjusting rod.

[0024] A further preferred technical solution is that the combined pipe unit further comprises a standby protruding block provided on the fixed pipe and used to support the extension pipe, and a downward sliding groove provided on the extension pipe and used to insert the standby protruding block.

[0025] A further preferred technical solution is that the combined pipe unit further includes a sliding gripping rod arranged on the outer annular surface of the extension pipe. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0038] The following description is only a preferred embodiment of the present invention and is not intended to limit the scope of the present invention.

[0039] As attached Figure 1-7As shown, a hanger for accumulation type powder spray coating, the structure includes a chain hook 11, a sling 12, and a workpiece hook 13, and is characterized in that it also includes a main frame unit 1 with upper and lower ends respectively used to install the chain hook 11 and the sling 12, a vertical blocking plate unit 2 and a horizontal blocking frame unit 3 respectively arranged at both sides of the main frame unit 1 and used to increase the distance between two adjacent workpieces a, and a combined pipe unit 4 arranged on the main frame unit 1 and used to sleeve the sling 12.

[0040] In this embodiment, the hanger is used together with a slidable connector d and a stopper e. The latter two are commercially available devices, and their function is to enable the hanger and the workpiece a to be accumulated upstream of the powder coating operation room b and placed as needed.

[0041] The slidable connector d and the conveyor belt c are movably connected, and the two can be separated from each other as long as the resistance on the hanger is sufficient. The gear lever e is connected to the motor and the control circuit, and can put in a suitable number of workpieces a as needed at the required time, ultimately ensuring that the accumulation and release conveyor line can operate effectively.

[0042] In addition, the outstanding functions of this hanger mainly include the following 4 points.

[0043] First, two adjacent hangers block each other through the vertical blocking plate unit 2 of one and the horizontal blocking frame unit 3 of the other, ensuring that the workpiece a is not easily damaged even in the accumulation waiting area of ​​the conveyor line with the highest workpiece density.

[0044] Second, the blocking distance is adjustable. When the size of workpieces a in a batch is relatively small, the blocking distance can be shortened, thereby increasing the workpiece accumulation capacity of the accumulation waiting area without being easily damaged.

[0045] Thirdly, also in the above-mentioned accumulation waiting area where the need to avoid swaying and collision is greatest, the combined pipe unit 4 can be largely sleeved on the sling 12 to increase the difficulty of swaying of the sling 12, thereby protecting the workpiece a.

[0046] Fourthly, the above-mentioned sleeve range can reduce the sleeve limit strength when the workpiece a is taken from the hanger, that is, when the anti-collision requirement is low, allowing the sling 12 to swing relatively widely, thereby facilitating the taking and placing operation of the workpiece a.

[0047] Finally, the chain hook 11, the sling 12 and the workpiece hook 13 are all commercially available products. The chain hook 11 and the workpiece hook 13 can be S-shaped or J-shaped, and the sling 12 can be a steel cable, a rope or a ring chain.

[0048] The main frame unit 1 includes a base plate 101 for installing the sling 12 and the vertical blocking plate unit 2, two vertical plates 102 respectively arranged at two sides of the base plate 101 and used to install the chain hook 11 and the horizontal blocking frame unit 3, and a reinforcing horizontal plate 103 whose two ends are respectively arranged on the two vertical plates 102 and used to install the vertical blocking plate unit 2.

[0049] In this embodiment, the bottom plate 101, the vertical plate 102 and the reinforcing horizontal plate 103 are integrally formed. The whole is fixedly connected with the chain hook 11, the sling 12, the vertical blocking plate unit 2 and the horizontal blocking frame unit 3, thereby ensuring sufficient suspension strength.

[0050] The vertical blocking plate unit 2 includes two transverse protruding plates 201 respectively arranged on the bottom plate 101 and the reinforcing transverse plate 103, and a vertical plate 202 of the transverse blocking frame unit 3 arranged on the two transverse protruding plates 201 and used to block the adjacent hangers.

[0051] In this embodiment, the vertical blocking plate unit 2 and the main frame unit 1 are integrally formed or fixed by welding at a later time.

[0052] When the hanger is installed on the conveyor belt c, it is necessary to ensure that the vertical blocking plate units 2 have a uniform orientation, that is, all facing the front of the conveyor or all facing the rear of the conveyor, thereby ensuring that between two adjacent hangers, the vertical blocking plate unit 2 must be against the horizontal blocking frame unit 3.

[0053] Compared with the mutual blocking method of the two vertical blocking plate units 2 or the two horizontal blocking frame units 3, the blocking effect of the above-mentioned blocking method of separating the workpieces a is more effective, and even if the hanger swings slightly back and forth or left and right, it will not affect the blocking effect.

[0054] The transverse blocking frame unit 3 includes two transverse tubes 301 respectively arranged on the two vertical plates 102, two insertion rods 302 respectively arranged on the two transverse tubes 301, and a movable transverse plate 303 arranged on the two insertion rods 302 and used to block the vertical blocking plate unit 2 of the adjacent hanger.

[0055] In this embodiment, the transverse tube 301 and the main frame unit 1 are integrally formed or welded.

[0056] The insert rod 302 can be inserted and pulled out and adjusted on the transverse tube body 301 to ensure that the accumulated workpieces a have a sufficient and as small spacing as possible, thereby ultimately increasing the workpiece accumulation capacity of the above-mentioned accumulation waiting area.

[0057] Accordingly, it is required that the insertion rod 302 and the transverse tube body 301 have sufficient and appropriate plug-in clamping strength.

[0058] The combined pipe unit 4 includes a fixed pipe 401 disposed on the bottom plate 101 and sleeved with the sling 12, and an extension pipe 402 sleeved on the outer annular surface of the fixed pipe 401 and used to sleeve the sling 12 by sliding down when the workpiece a is moved and transported.

[0059] In this embodiment, the fixing tube 401 and the main frame unit 1 are integrally formed or welded.

[0060] When the extension tube 402 is largely sleeved on the fixed tube 401, the sling 12 can be allowed to have a larger swing amplitude. At this time, the corresponding state of the hanger is that the workpiece a is being picked up and placed, and the inclined sling 12 can make the workpiece picking and placing operation more convenient. Of course, at this time, the workpiece a is in a relatively sparse position on the conveyor belt c, not in the above-mentioned accumulation area, and there is almost no need to prevent damage.

[0061] When the extension tube 402 is slightly sleeved with the fixed tube 401, the former has properly slid down. At this time, even if the sling 12 swings, its allowable amplitude is relatively small, thereby avoiding collision and damage between adjacent workpieces a. This is particularly important in the above-mentioned accumulation area.

[0062] The downward movement of the extension tube 402 can be manually completed by an operator after the workpiece a is hung.

[0063] The main frame unit 1 further includes a hanging hole 104 for adding a counterweight, which is arranged on the bottom plate 101 .

[0064] In this embodiment, the added counterweight hanging hole 104 is used to additionally hang a counterweight block of appropriate weight, so that the hanger has a basic anti-swaying function.

[0065] The transverse blocking frame unit 3 further includes a plurality of adjustment holes 304 arranged on the transverse tube body 301 , a mounting hole 305 arranged on the insertion rod 302 , and an adjustment rod 306 arranged on the adjustment hole 304 and the mounting hole 305 .

[0066] In this embodiment, the adjustment holes 304 are arranged in pairs, with the number being 4-8 pairs, to ensure that the transverse blocking frame unit 3 has multiple blocking effects with different protruding amplitudes.

[0067] Generally, if the workpiece a is relatively large and the impact action is relatively easy, the adjustment rod 306 needs to be inserted into the relatively outer adjustment hole 304. At this time, the movable horizontal plate 303 is relatively far away from the main frame unit 1, and vice versa.

[0068] The transverse blocking frame unit 3 further includes an anti-drop block 307 arranged on the upper end surface of the adjusting rod 306 .

[0069] In this embodiment, the adjustment rod 306 and the anti-drop block 307 together form a "T-shaped" structure, the size of the latter is larger than the adjustment hole 304, thereby ensuring that the transverse blocking frame unit 3 will not shrink and shorten spontaneously in the absence of external force.

[0070] The number of the mounting holes 305 is one, and by aligning and plugging any one pair of the adjustment holes 304 , it can be ensured that the movable horizontal plate 303 can fully resist the vertical plate 202 .

[0071] The combined pipe unit 4 further includes a standby protruding block 403 disposed on the fixed pipe 401 and used to support the extension pipe 402 , and a downward sliding groove 404 disposed on the extension pipe 402 and used to insert the standby protruding block 403 .

[0072] In this embodiment, the standby protrusion 403 is arranged relatively lower on the fixed tube 401, and the downward sliding groove 404 is opened upward from the lower surface of the extension tube 402 and cannot penetrate the entire extension tube 402. The vertical length of the downward sliding groove 404 is the maximum downward sliding dimension of the extension tube 402.

[0073] When the positioning protrusion 403 enters the downward sliding groove 404 , it is generally directly located at the highest point in the downward sliding groove 404 , ensuring that the extension tube 402 can be connected with the fixed tube 401 to restrict the sling 12 .

[0074] It should be noted that the above-mentioned limiting strength mainly depends on the material rigidity of the combined pipe unit 4 and the sleeve accuracy of the extension pipe 402 and the fixed pipe 401. The combined pipe unit 4 cannot completely prevent the swing of the sling 12, but can only appropriately reduce the swing amplitude of the sling 12 and the workpiece a to avoid damage to the workpiece a as much as possible.

[0075] The combined pipe unit 4 further includes a downward sliding gripping rod 405 disposed on the outer annular surface of the extension pipe 402 .

[0076] In this embodiment, the downward-sliding gripping rod 405 is used to relatively conveniently rotate, slide down, and open the extension tube 402, or to raise, rotate, and retract the extension tube 402 after being gripped.

[0077] In addition, the anti-slip strip 406 made of ordinary rubber material is also provided on the lower surface of the extension tube 402 to ensure that the extension tube 402 is prevented from falling after spontaneous rotation when the workpiece a is normally taken and placed and the sling 12 is likely to be tilted.

[0078] The above is a detailed description of the implementation of the utility model in conjunction with the accompanying drawings, but the utility model is not limited to the above implementation. Various modifications can be made within the knowledge of ordinary technicians in the technical field without departing from the purpose of the utility model. These are all non-creative modifications and are protected by patent law as long as they are within the scope of the claims of the utility model.
