Description

Technical Field

[0001] This application relates to the field of PET production technology, and in particular to a wooden fixture for testing the shear force of PET sheets. Background Technology

[0002] PET sheets are widely used in textiles, papermaking, food machinery, transportation, docks, medical, coal mining, chemical and other industries.

[0003] During the production of PET sheets, it is necessary to test the shear strength of the PET sheets. During the test, a wooden board is placed at the edge of the lower surface of the PET sheet to suspend the PET sheet, which facilitates the testing of the shear strength of the PET sheet. To prevent the wooden board from slipping, glue is applied between the wooden board and the PET sheet.

[0004] The existing technical solutions mentioned above have the following drawbacks: due to the small contact area between the wood board and the PET board and the small area for applying glue, the wood board and the PET board may not be firmly bonded, which may hinder the shearing of the PET board. Utility Model Content

[0005] This application provides a wooden board fixture for testing the shear force of PET boards in order to make the adhesion between PET boards and wooden boards more secure.

[0006] The above-mentioned technical objective of this application is achieved through the following technical solution:

[0007] A wooden board fixture for testing the shear force of PET boards includes a base plate, a telescopic cylinder connected to the base plate, the piston rod of the telescopic cylinder facing downward, a template connected to the piston rod of the telescopic cylinder, and a plurality of needles disposed on the end of the template away from the telescopic cylinder.

[0008] By adopting the above method, the wooden board is placed on top of the substrate, and then the piston rod of the telescopic cylinder extends, so that the needle punches a hole in the surface of the wooden board. Then, glue is applied to the surface of the wooden board. Since there are multiple holes in the wooden board panel, the glue enters into the holes, so that there is more glue between the wooden board and the PET board when the wooden board and the PET board are bonded, thus making the PET board and the wooden board bond more firmly.

[0009] Optionally, the needles are arranged in an array, with multiple needles evenly distributed on the side of the needles away from the telescopic cylinder.

[0010] By adopting the above method, the glue is distributed more evenly on the surface of the wood board, thus ensuring that the PET board is firmly bonded to all parts of the wood board surface.

[0011] Optionally, the substrate is provided with a fixing structure for fixing the wooden board.

[0012] By adopting the above solution and fixing the wooden board with a fixed structure, the process of punching holes in the wooden board is made smoother, and the process of punching holes is prevented from being hindered by the wooden board and the template being connected together.

[0013] Optionally, the fixing structure includes a fixing plate, the upper surface of which is provided with a sliding groove, and a bidirectional lead screw is rotatably connected in the sliding groove. The fixing plate is provided with two clamping plates, each clamping plate is connected with a threaded sleeve for connecting with the bidirectional lead screw, and the two clamping plates are respectively located near the two ends of the bidirectional lead screw.

[0014] By adopting the above method, when it is necessary to punch holes in the template, the wooden board is placed on top of the fixed plate, and then the two-way screw is rotated to bring the two clamping plates closer together, thereby clamping the wooden board and fixing it, which makes it easier to punch holes.

[0015] Optionally, a slide rail is provided above the substrate, allowing the fixing plate to slide along the slide rail.

[0016] By adopting the above solution, when placing the wooden board, the fixing plate can be slid along the slide rail first, so that the fixing plate slides away from directly under the template, and then the wooden board is placed on top of the fixing plate. This makes it easier for the operator to place the wooden board on the fixing plate, and also prevents the needles from piercing the operator and causing safety hazards when placing the wooden board.

[0017] Optionally, the slide rail surface has a through hole, and the fixing plate surface has an insertion hole. When the fixing plate is located directly below the template, the through hole and the insertion hole are aligned, and an insertion rod is inserted into the insertion hole through the through hole.

[0018] By adopting the above method, after the wooden board is fixed above the fixing plate, the fixing plate is slid to the bottom of the template, and then the insertion rod is inserted through the through hole and into the insertion hole to fix the fixing plate, making it easier to punch holes in the wooden board.

[0019] Optionally, the piston rod of the telescopic cylinder is fixedly connected to a connecting plate, the connecting plate has a threaded hole, the template surface has a threaded hole, and the connecting plate and the template are connected by bolts.

[0020] By adopting the above solution, when connecting the connecting plate and the template with bolts, and when it is necessary to drill holes in wooden boards of different specifications, the template can be removed and replaced.

[0021] In summary, this application has the following technical effects:

[0022] 1. By setting up telescopic cylinders and templates, holes are punched in the surface of the wood board, allowing more glue to be applied to the surface of the wood board, thus making the adhesion between the wood board and the PET board stronger;

[0023] 2. The installation of a fixing structure makes it easier to drill holes in the wooden board;

[0024] 3. The addition of sliding rails makes it easier to fix the wooden board to the fixed plate. Attached Figure Description

[0030] The present application will be further described in detail below with reference to the accompanying drawings.

[0031] Reference Figure 1 , Figure 2 and Figure 3 A fixture for testing the shear force of PET boards using a wooden board 6 includes a base plate 1. A telescopic cylinder 2 is connected to the base plate 1, with the piston rod of the telescopic cylinder 2 facing downwards. The piston rod of the telescopic cylinder 2 is connected to a template 3, and multiple needles 31 are provided on the end of the template 3 facing away from the telescopic cylinder 2. The wooden board 6 is placed on top of the base plate 1, and then the piston rod of the telescopic cylinder 2 extends, causing the needles 31 to poke holes in the surface of the wooden board 6. Glue is then applied to the surface of the wooden board 6. Because there are multiple holes in the wooden board 6, the glue enters into the holes, resulting in more glue between the wooden board 6 and the PET board when they are bonded, thus making the bond between the PET board and the wooden board 6 more secure.

[0032] Reference Figure 2 and Figure 3 The adhesive needles 31 are arranged in an array on the end of the template 3 away from the telescopic cylinder 2. Multiple needles 31 are evenly distributed on the side away from the telescopic cylinder 2, ensuring a more even distribution of adhesive on the surface of the wooden board 6, thus guaranteeing a firm bond between the wooden board 6 and the PET board. A connecting plate 21 is fixedly connected to the piston rod of the telescopic cylinder 2. The connecting plate 21 has threaded holes, and threaded holes are also present on the surface of the template 3. The connecting plate 21 and the template 3 are connected by bolts. This facilitates the replacement of the template 3.

[0033] Reference Figure 2 and Figure 3 The base plate 1 is provided with a fixing structure 4 for fixing the wooden board 6. The fixing structure 4 includes a fixing plate 41, the upper surface of which has a groove 411. A bidirectional lead screw 42 is rotatably connected within the groove 411. The fixing plate 41 is provided with two clamping plates 43, each clamping plate 43 being connected to a threaded sleeve 431 for connecting to the bidirectional lead screw 42. The two clamping plates 43 are located near both ends of the bidirectional lead screw 42. When it is necessary to punch holes in the template 3, the wooden board 6 is placed on the fixing plate 41, and then the bidirectional lead screw 42 is rotated to bring the two clamping plates 43 closer together, thereby clamping the wooden board 6 and fixing it for easy punching. In addition, templates 3 of different sizes can be clamped by the clamping plates 43.

[0034] Reference Figure 3 and Figure 4 A slide rail 5 is provided on the top of the substrate 1. There are two slide rails 5, which are located on opposite sides of the fixing plate 41. The fixing plate 41 is slidably connected to the slide rail 5, and a through hole 51 is provided on the surface of the slide rail 5. Insertion holes 412 are provided on both sides of the fixing plate 41 connected to the slide rail 5. When the fixing plate 41 is located directly below the template 3, the through hole 51 and the insertion hole 412 are directly opposite each other. An insertion rod 52 is provided to pass through the through hole 51 and insert into the insertion hole 412, thereby fixing the fixing plate 41, so that it is easier to punch holes in the wooden board 6.

[0035] The specific implementation principle of this application is as follows: When a shear force test is required on a PET board, the wooden board 6 is placed above the fixed plate 41. Then, the bidirectional screw 42 is rotated to bring the two clamping plates 43 closer together, thereby clamping the wooden board 6. Then, the fixed plate 41 is slid along the slide rail 5 so that the wooden board 6 reaches directly below the template 3. Then, the insertion rod 52 is inserted into the insertion hole 412 through the through hole 51, thereby fixing the fixed plate 41. Then, the piston rod of the telescopic cylinder 2 extends, so that the piercing needle 31 is inserted into the wooden board 6, forming a hole on the surface of the wooden board 6. Then, the wooden board 6 is removed, and glue is applied to the surface of the wooden board 6 on the side with the hole. Then, the glued side of the wooden board 6 is glued to the PET board. Since the hole is filled with glue, the adhesion between the wooden board 6 and the PET board is stronger.

After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this application.
