Description

Technical Field

[0001] The utility model belongs to the field of plastic product processing, and particularly relates to a compressive strength detection device for plastic products. Background Technique

[0002] The compressive strength detection in the production of plastic products is a test to evaluate the performance and pressure resistance of plastic materials or products when subjected to vertical pressure. This detection is usually used to ensure that plastic products can withstand the required loads during actual use and prevent deformation, rupture or failure caused by excessive compression. Compressive strength detection plays an important role in the quality control and material selection of plastic products. Through compressive strength testing, the mechanical properties of plastic materials can be understood, including their strength, stiffness and ductility, etc. This helps to select materials suitable for specific applications.

[0003] At present, most of the pressure testing devices applied to plastic products use special fixed molds to fix the plastic products on the pressure testing table. When the size of the plastic products to be subjected to pressure testing changes, only the fixed molds can be replaced to fix the plastic products. This method not only requires a large number of prefabricated fixed molds, resulting in an increase in usage costs, but also affects a certain production efficiency in a cost-effective factory. Therefore, considering the compressive strength detection efficiency and cost-effectiveness of plastic products, a compressive strength detection device for plastic products is proposed to solve the above problems. Content of the Utility Model

[0006] A vertical platform is vertically assembled and arranged on the pressure testing seat; a plastic product compressive strength testing machine is installed on the side of the vertical platform;

[0007] Four support shafts are arranged in a rectangular shape on the upper end surface of the pressure testing seat, and a support seat is jointly carried on the upper end surfaces of the four support shafts, and a pressure testing table is carried on the support seat;

[0009] The plastic product limiting assembly includes a limiting frame disposed on the upper end surface of the pressure test bench. The limiting frame has a rectangular frame structure, and positioning seats are integrally provided on both of its transverse sides. The positioning seats are U-shaped, and connecting seats are slidably disposed thereon. A slider seat is installed on the connecting seat, and a limiting shaft is vertically provided on the upper end surface of the slider seat.

[0010] As a further improvement of the present utility model, a reciprocating motor is assembled and provided on the upper end surface of the positioning seat, and a threaded lead screw is connected to the output end of the reciprocating motor; the threaded lead screw penetrates through the slider seat and is meshed with it.

[0011] As a further improvement of the present utility model, four rotating shaft seats are arranged in a rectangular shape on the upper end surface of the limiting frame, and a bearing shaft is assembled and provided on each rotating shaft seat.

[0012] As a further improvement of the present utility model, rubber sleeves are sleeved on the outer parts of the two limiting shafts.

[0013] As a further improvement of the present utility model, a guide rod cylinder is assembled and provided on the vertical platform, and a pressure test camera is connected to the output end of the guide rod cylinder. The pressure test camera is disposed on one side of the plastic product limiting assembly.

[0014] Generally speaking, compared with the prior art by the above technical solutions conceived by the present utility model, the beneficial effects include:

[0015] In actual use, the plastic product compressive strength detection device of the present utility model can realize the clamping and limiting of plastic products by using two oppositely sliding limiting shafts through the mutual movement and cooperation of multiple components in the two sets of plastic product limiting assemblies provided, so as to finally realize the limiting and bearing of plastic products in cooperation with the bearing of the bearing shafts.

[0016] In the actual use of the plastic product compressive strength testing equipment of the present utility model, the guide rod cylinder provided can be used to adjust the stroke of the pressure test camera. Thus, when the plastic product compressive testing machine conducts compressive tests on plastic products of different sizes, the provided pressure test camera can monitor the deformation and damage conditions of the plastic products during the compressive test in real time, providing an intuitive video record, which is convenient for subsequent analysis and evaluation of the deformation modulus of the plastic products under compressive tests.

[0022] Embodiment

[0023] Provided by Figures 1-3 A plastic product compressive strength testing equipment includes a pressure test seat 1;

[0024] A vertical platform 2 is vertically assembled and provided on the pressure test seat 1; a plastic product compressive testing machine 3 is installed on the side of the vertical platform 2;

[0025] The upper end surface of the pressure test base 1 is provided with four support shafts 11 in a rectangular shape. The upper end surfaces of the four support shafts 11 jointly carry a support base 12, and a pressure test table 4 is carried on the support base 12.

[0026] A plastic product limiting component 5 is carried on the upper end surface of the pressure test table 4.

[0027] Among them, the plastic product limiting component 5 includes a limiting frame 51 arranged on the upper end surface of the pressure test table 4. The limiting frame 51 is in a rectangular frame structure, and positioning seats 52 are integrally arranged on both of its transverse sides. The positioning seats 52 are in a U shape, and a connecting seat 56 is slidably arranged thereon. A slider seat 55 is installed on the connecting seat 56, and a limiting shaft 57 is vertically arranged on the upper end surface of the slider seat 55.

[0028] In this embodiment, in actual use, through the mutual movement cooperation of multiple components in the two sets of plastic product limiting components 5 provided, the clamping and limiting of plastic products can be realized by using two oppositely sliding limiting shafts 57, so as to finally realize the limiting and bearing of plastic products in cooperation with the bearing of the bearing shaft 59. Compared with the traditional mold positioning method, when the anti-pressure detection equipment for plastic products of the present application conducts anti-pressure tests on plastic products, the two sets of plastic product limiting components 5 can be used to adjust plastic products of different sizes, so as to flexibly clamp plastic products of various specifications; this adaptability makes the anti-pressure test process more efficient, reduces the frequent replacement of molds, and at the same time, the two sets of plastic product limiting components 5 provided can provide uniform clamping force to ensure that the plastic products will not slide or shift during the test, thereby improving the accuracy and repeatability of the test.

[0029] Specifically, referring to Figures 2-3 , a reciprocating motor 53 is assembled on the upper end surface of the positioning seat 52, and the output end of the reciprocating motor 53 is connected with a threaded lead screw 54; the threaded lead screw 54 penetrates through the slider seat 55 and is meshed with it.

[0030] In this embodiment, in use, the provided reciprocating motor 53 can be used to control the rotation of the threaded lead screw 54. The user connects a power supply to the reciprocating motor 53. At this time, the provided reciprocating motor 53 can drive the threaded lead screw 54 connected thereto to rotate. When the threaded lead screw 54 rotates, limited by the positioning seat 52 to the connecting seat 56, the slider seat 55 meshed with the threaded lead screw 54 can drive the whole connecting seat 56 to move horizontally along the stroke range of the threaded lead screw 54.

[0031] Furthermore, the reciprocating motor 53 and the plastic product compressive testing machine 3 provided are both mature equipment parts in the existing market. Their power connection methods are in the prior art, and the control circuit can be realized by simple programming by those skilled in the art, which belongs to the common general knowledge in the art. Only their use is involved without modification, so the control method and circuit connection will not be described in detail.

[0032] Specifically, referring to Figures 2-3 , four rotating shaft seats 58 are arranged in a rectangular shape on the upper end surface of the limit frame 51, and a bearing pressure shaft 59 is assembled on each rotating shaft seat 58.

[0033] In this embodiment, the rotating shaft seats 58 provided can be used to install the bearing pressure shafts 59. During use, the plastic products to be tested are placed on the four bearing pressure shafts 59, and the plastic products are initially borne by the four bearing pressure shafts 59.

[0034] Specifically, referring to Figure 3 , rubber sleeves are sleeved on the outer parts of the two limit shafts 57.

[0035] In this embodiment, the rubber sleeves provided on the outer parts of the limit shafts 57 can avoid clamping damage to the plastic products during clamping, thereby improving the clamping safety of the plastic products. At the same time, the rubber sleeves provided can further prevent the plastic products from moving during clamping, so as to stably clamp the plastic products for compressive testing.

[0036] Specifically, referring to Figures 1-2 , a guide rod cylinder 6 is assembled on the vertical platform 2, and a pressure test camera 7 is connected to the output end of the guide rod cylinder 6. The pressure test camera 7 is arranged on one side of the plastic product limiting assembly 5.

[0037] In this embodiment, during actual use, the guide rod cylinder 6 provided can be used to adjust the stroke of the pressure test camera 7. The user can connect the guide rod cylinder 6 to an external air source, and then the output end of the guide rod cylinder 6 can drive the pressure test camera 7 to move. Thus, when the plastic product compressive testing machine 3 conducts compressive tests on plastic products of different sizes, the provided pressure test camera 7 can monitor the deformation and damage conditions of the plastic products during the compressive test in real time, provide an intuitive video record, and facilitate subsequent analysis and evaluation of the deformation modulus of the plastic products under compressive tests.

[0038] Further preferably, in actual use, the guide rod cylinder 6 can be rotatably installed on the vertical platform 2 by a rotary motor cooperating with a cylinder seat. By controlling the rotation angle of the rotary motor, the angle adjustment of the guide rod cylinder 6 can be achieved. During this period, by adjusting the installation angle of the guide rod cylinder 6 and cooperating with the stroke adjustment of the guide rod cylinder 6 for the pressure test camera 7, the pressure test camera 7 can observe the plastic product more comprehensively, and the compressive characteristics of the plastic product material can be analyzed from different angles.

[0039] The plastic product compressive strength testing equipment of the present utility model:

[0040] First step: In actual use, when the user needs to conduct a compressive test on a plastic product, the plastic product to be tested is placed on the four bearing shafts 59, and the four bearing shafts 59 initially bear the plastic product. Subsequently, the user connects the power supply to the two reciprocating motors 53. At this time, the set reciprocating motor 53 can drive the threaded lead screw 54 connected thereto to rotate. When the threaded lead screw 54 rotates, due to the limitation of the positioning seat 52 on the connecting seat 56, the slider seat 55 engaged with the threaded lead screw 54 can drive the entire connecting seat 56 to move horizontally along the stroke range of the threaded lead screw 54, thereby driving the horizontal movement of the limiting shaft 57 by the movement of the connecting seat 56.

[0041] Second step: The user can make the two connecting seats 56 drive the limiting shafts 57 to perform an opposing clamping movement or a reverse release movement by controlling the forward and reverse rotation directions of the threaded lead screw 54. The user controls the two limiting shafts 57 to perform an opposing clamping until the two limiting shafts 57 abut against the side wall of the plastic product. At this time, the clamping and limiting of the plastic product can be achieved by using the limiting shafts 57.

[0042] Third step: After the plastic product is clamped and limited by the plastic product limiting assembly 5, the user can drive the plastic product compressive strength testing machine 3 at this time, so that its test end moves downward to contact the upper part of the plastic product. Through the downward pressure of the plastic product compressive strength testing machine 3, the compressive test of the plastic product is finally realized. At the same time, the set pressure test camera 7 can cooperate with the plastic product compressive strength testing machine 3 to accurately record the deformation amount generated by the plastic product during the test, so as to facilitate the user to record.

[0043] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
