[0032] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.
[0033] The following is a reference to the appendix. Figures 1 to 5 This invention provides a detailed description of the constraint fixture 100 and the washing equipment according to embodiments of the present invention.
[0034] The washing equipment of this utility model includes a main body and a constraint fixture 100. The main body has a conveyor belt, and the constraint fixture 100 is placed on the conveyor belt.
[0035] like Figure 1 , Figure 2 and Figure 5 As shown, the constraint fixture 100 of this embodiment includes a limiting frame 1 and a receiving mesh 2. The limiting frame 1 has an inner cavity, which is located in a first direction (e.g., Figure 1 Both sides of the inner cavity (in the height direction) are open. The receiving mesh 2 is connected to the limiting frame 1. The receiving mesh 2 is located on one side of the inner cavity in the first direction. The receiving mesh 2 has several through holes. One side of the inner cavity is connected to the outside through the through holes. The receiving mesh 2 and the inner cavity form a storage space 3 on the other side of the first direction. The storage space 3 is used to place lightweight pultruded strips. The limiting frame 1 is used to connect with the conveyor belt of the washing equipment.
[0036] When using the constraint fixture 100 of this utility model embodiment, the receiving net 2 is located on the lower side of the limiting frame 1, and the upper side of the storage space 3 is open. Multiple pultruded strips are placed in the storage space 3 and laid flat on the receiving net 2. Then the constraint fixture 100 is placed on the conveyor belt of the washing equipment. The conveyor belt drives the constraint fixture 100 and the pultruded strips inside to move, and the body cleans the pultruded strips.
[0037] The constraint fixture 100 of this utility model forms a storage space 3 through the limiting frame 1 and the receiving net 2. The receiving net 2 forms a lower limit on the pultruded strip, and at the same time, the receiving net 2 is provided with several through holes to facilitate the passage of water and air, thereby facilitating the water flow to wash the pultruded strip and discharge through the receiving net 2 after washing. This allows the body to continuously wash the pultruded strip, and at the same time, maintains a uniform frequency in vibration with the pultruded part. The limiting frame 1 forms a horizontal limit on the pultruded strip, preventing the lightweight pultruded strip from moving outside the constraint fixture 100, and preventing the pultruded strip from having a hard collision or contact with the body. This can effectively solve the problem of parts getting stuck and stacked inside the body of the lightweight pultruded strip, eliminate the product scrap rate, and improve the product cleaning efficiency.
[0038] Therefore, the constraint fixture 100 of this utility model embodiment can form a larger whole with the pultruded part during the cleaning and moving process of the main body, preventing the pultruded part from making hard contact with the main body, effectively solving the problem of light products getting stuck or stacked in the equipment, eliminating product scrap rate and improving product cleaning efficiency.
[0039] As one embodiment of the constraint fixture 100 of this utility model, such as Figure 1 and Figure 2 As shown, the limiting frame 1 is a square frame with four bends 11, which are arc-shaped. The arc-shaped bends 11 have smooth surfaces, so that when the constraint fixture 100 moves on the conveyor belt, it avoids jamming with the baffles and seams on the conveying path inside the body, thus ensuring the normal movement of the constraint fixture 100 inside the body.
[0040] As one embodiment of the constraint fixture 100 of this utility model, such as Figure 5 As shown, the limiting frame 1 is a square frame with four corners 11. The limiting frame 1 is in the second direction (such as...). Figure 5 The dimension in the front-to-back direction is larger than its dimension in the third direction (e.g., Figure 5 The constraint fixture 100 further includes guide plates 6, and guide plates 6 are provided at both ends of the corner 11 of the limiting frame 1 in the second direction. One end of the guide plate 6 is connected to the limiting frame 1. The guide plate 6 has an arc segment that extends from the one end to the other end of the guide plate 6. The other end or part of the guide plate 6 faces the middle of the limiting frame 1 in the third direction. The arc-shaped section of the guide plate 6 has a smooth surface, and the arc-shaped section is connected to the bend 11 of the limiting frame 1. Thus, when the constraint fixture 100 moves on the conveyor belt, it avoids jamming with the baffles and seams on the conveying path inside the main body. In addition, the guide plate 6 has a certain strength. One end of the guide plate 6 is connected to the limiting frame 1, and the other end is suspended, which also gives the guide plate 6 a certain degree of flexibility and deformation space. When constrained or impacted, it can avoid the impact point by deforming itself and / or pushing the constraint fixture 100 as a whole to move, thus avoiding jamming with the baffles and seams on the conveying path inside the main body and ensuring the normal movement of the constraint fixture 100 inside the main body.
[0041] In some embodiments, such as Figure 5 As shown, guide plate 6 is a quarter-circle guide plate 6.
[0042] In other embodiments, such as Figure 6 As shown, the other end of the guide piece 6 is rolled up towards the limiting frame 1. For example, the guide piece 6 is in the shape of a "6". The middle part of the guide piece 6 abuts against or is adjacent to the limiting frame 1, so that when the guide piece 6 is deformed, the sharp corner or cross-section of the end of the guide piece 6 will not abut against the limiting frame 1 and scratch the limiting frame 1.
[0043] Specifically, it is made of metal materials, for example, the guide plate 6 is an aluminum alloy sheet, or the guide plate 6 is a galvanized iron sheet.
[0044] In some embodiments, such as Figure 3As shown, the constraint fixture 100 further includes a first partition 4, which extends along a second direction. Multiple first partitions 4 are arranged at intervals along a third direction within the storage space 3. The first partitions 4 are connected to the limiting frame 1, and the third direction is orthogonal to both the second and first directions. The multiple first partitions 4 divide the storage space 3 into multiple smaller first partition spaces 31 along the third direction. Each first partition space 31 contains a pultruded strip, thereby reducing the space occupied by a single pultruded strip along the third direction and further restricting the movement space of the pultruded strip. This avoids the possibility of pultruded strips accumulating or crossing within the storage space 3, thus ensuring the cleaning effect of the fixture on the pultruded strips and guaranteeing the cleanliness rate of the pultruded strips.
[0045] Specifically, the limiting frame 1 has multiple first grooves at both ends in the second direction, and the first partition 4 has first protrusions 41 at both ends in the second direction. The first protrusions 41 are fitted into the first grooves.
[0046] Specifically, the first partition 4 is connected to the receiving mesh 2 on one side in the first direction, thereby increasing the strength of the receiving mesh 2 and preventing deformation of the receiving mesh 2. This, in turn, helps to improve the stability of the constraint fixture 100 in limiting the pultruded strip, improves the integrity of the constraint fixture 100 and the pultruded strip, and thus ensures the stability of the pultruded strip during the cleaning and movement process, and ensures the cleanliness of the pultruded strip.
[0047] In some embodiments, such as Figure 3 As shown, the constraint fixture 100 further includes a second partition 5 extending along a third direction. Multiple second partitions 5 are spaced apart within the storage space 3 along a second direction. The ends of the second partitions 5 are connected to the limiting frame 1, and the second partitions 5 are connected to the first partition 4. The multiple second partitions 5 divide the first partition space 31 into multiple smaller second partition spaces 32. Each second partition space 32 contains a pultruded strip, thereby further reducing the space occupied by a single pultruded strip in the second direction and further restricting the movement space of the pultruded strip. This avoids the possibility of pultruded strips accumulating or crossing within the storage space 3, thereby ensuring the cleaning effect of the body on the pultruded strips and guaranteeing the cleanliness rate of the pultruded strips.
[0048] Specifically, such as Figure 4 As shown, the first partition 4 has a first slot 42, and the second partition 5 has a second slot 52. The second slot 52 is opposite to the first slot 42, and the second partition 5 and the first partition 4 are fastened together by the first slot 42 and the second slot 52. The connection structure of the first partition 4 and the second partition 5 is simple and easy to process and assemble.
[0049] Specifically, the limiting frame 1 has multiple second grooves at both ends in the third direction, and the second partition 5 has second protrusions 51 at both ends in the third direction. The second protrusions 51 are fitted into the second grooves. The second partition 5 is connected to the limiting frame 1, thereby increasing the connection strength between the limiting frame 1, the second partition 5, and the first partition 4, and increasing the integrity of the limiting frame 1, the second partition 5, and the first partition 4, thus improving the stability and reliability of the constraint fixture 100 of this utility model during use.
[0050] Optionally, the number of second partitions 5 is two to four and they are evenly arranged. Then, the second partition space 32 is a long and narrow space, similar to the shape of a long and narrow pultruded part, which is conducive to the reasonable division of the storage space 3 for batch storage of pultruded parts.
[0051] Specifically, such as Figure 3 As shown, there are three second partitions 5.
[0052] Specifically, such as Figure 1 As shown, the outer contour of the limiting frame 1 has a dimension of 900mm in the second direction and 550mm in the third direction. The inner contour of the limiting frame 1 has a dimension of 860mm in the second direction and 510mm in the third direction. The limiting frame 1 is made of galvanized iron pipe with a cross-sectional dimension of 20mm*20mm. The through-hole size of the mesh 2 is 8*8mm-10*140mm.
