Description

Technical Field

[0001] This utility model relates to the field of testing device technology, and in particular to an opening and closing testing device for a fermentation chamber door. Background Technology

[0002] A fermentation box, also known as a proofing box, is used for proofing baked goods. The frame structure of a fermentation box includes the box body and a door that rotates and connects to the body. The box body is usually made of stainless steel. To facilitate clear observation of the fermentation process inside, the door is typically a large glass door with a large tempered glass pane, which increases the door's weight. To ensure the reliability of fermentation boxes, a testing device is urgently needed to test the opening and closing performance of the fermentation box door. Utility Model Content

[0003] Therefore, it is necessary to provide a fermentation chamber door opening and closing test device to address the problem that it is difficult to test the opening and closing performance of fermentation chamber doors in the existing technology.

[0004] The technical solution adopted in this utility model is as follows:

[0005] A fermentation chamber door opening and closing test device includes a rotary cylinder fixed on the chamber body and a slide groove fixed on the chamber door;

[0006] The output end of the rotary cylinder is connected to one end of the swing rod, and the other end of the swing rod is installed in conjunction with the slide groove through a rolling connection mechanism. The rotary cylinder drives the swing rod to perform reciprocating rotation, thereby causing the swing rod to slide in the slide groove through the rolling connection mechanism, which in turn drives the door to open and close relative to the box body.

[0007] As a further improvement to the above technical solution:

[0008] The structure of the rolling connection mechanism is as follows: it includes a bearing, the inner ring of the bearing is fitted with the outer circumferential surface of the connecting pin, the outer ring of the bearing is fitted with a sliding groove, and the connecting pin is fixed to the rocker arm by a locking nut.

[0009] The end of the swing arm is provided with a connecting hole, which is used for connecting pin installation.

[0010] The bearing is fixed to the connecting pin by a locking bolt, and a washer is installed between the locking bolt and the bearing.

[0011] A protrusion is provided circumferentially on the outer circumferential surface of the connecting pin. The protrusion supports the inner ring of the bearing, thereby separating the bearing from the rocker arm.

[0012] The rotation angle range of the swing arm is 0°-90°.

[0013] The slide is in the form of a groove handle.

[0014] The input end of the rotary cylinder is connected to an external air source through a connecting pipe assembly, thereby supplying air to the rotary cylinder through the external air source. An air source processing device and a solenoid valve are installed in sequence on the connecting pipe assembly. The solenoid valve controls the rotation direction of the rotary cylinder under the action of an external controller, thereby causing the rocker arm to rotate forward or backward.

[0015] The gas source processing device adopts a pneumatic dual unit.

[0016] The rotary cylinder is fixed to the housing by a cylinder bracket.

[0017] The beneficial effects of this utility model are as follows:

[0018] This utility model has a compact and reasonable structure and is easy to operate. By setting a rotary cylinder, a swing rod, a rolling connection mechanism and a slide, it can simulate the opening and closing action of the box door in actual use, realize automated testing, and thus effectively evaluate the strength and durability of the box door under long-term use, ensuring that the box door can meet the usage requirements and guarantee the stability and safety of the fermentation environment for baked goods.

[0019] This utility model also has the following advantages:

[0020] (1) By setting a slide groove, connecting pin and bearing, the swing arm can slide in the slide groove, so that the total length of the slide groove and the swing arm can be adjusted, thereby ensuring the stability of the swing arm driving the door to open and close.

[0021] (2) By setting a protrusion, the outer ring of the bearing is separated from the top wall of the rocker arm, thereby ensuring that the bearing can rotate smoothly.

[0022] (3) By setting up a solenoid valve, the flow direction of compressed air can be changed according to the control signal of the external controller, thereby changing the rotation direction of the rotary cylinder.

[0023] (4) By setting up an air source treatment device, the compressed air can be adjusted to a suitable pressure range and filtered.

[0024] (5) By setting a conductive film on the inside of the glass of the box door, the conductive film is heated by electricity, which can eliminate water vapor on the box door and prevent water vapor generated during food fermentation from adhering to the glass and affecting the user's observation of the inside of the fermentation box.

[0033] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0034] The structure and function of this utility model are as follows:

[0035] like Figures 1-6 As shown, a fermentation chamber door opening and closing test device includes a rotary cylinder 1 fixed to the chamber body 10 and a slide groove 5 fixed to the door 11. The output end of the rotary cylinder 1 is connected to one end of a swing rod 2, and the other end of the swing rod 2 is installed in conjunction with the slide groove 5 through a rolling connection mechanism 3. The rotary cylinder 1 drives the swing rod 2 to reciprocate, thereby causing the swing rod 2 to slide within the slide groove 5 through the rolling connection mechanism 3, which in turn drives the door 11 to open and close relative to the chamber body 10. By setting the rotary cylinder 1, swing rod 2, rolling connection mechanism 3 and slide groove 5, the opening and closing actions of the door 11 in actual use can be simulated, realizing automated testing, thereby effectively evaluating the strength and durability of the door 11 under long-term use, ensuring that the door 11 can meet the usage requirements, and guaranteeing the stability and safety of the fermentation environment for baked goods.

[0036] The fermentation box of this utility model includes a door 10 and a box body 11. Support frames 12 are installed on the upper and lower sides of the front of the box body 11. Each support frame 12 and the door 10 are connected by a threaded connector, thereby realizing the rotational installation between the door 10 and the box body 11. In addition, a conductive film is attached to the inside of the glass of the door 10. The conductive film is heated by electricity, which can eliminate water vapor on the door 10 and prevent water vapor generated during food fermentation from adhering to the glass and affecting the user's observation of the internal conditions of the fermentation box.

[0037] The conductive film is electrically connected to the drive power supply arranged outside the housing 10 via a cable. A hole is made in the support frame 12 mounted above the housing 11, so that the cable can be led out to the outside of the housing 10 through the through hole in the support frame 12.

[0038] like Figures 3-4 As shown, the structure of the rolling connection mechanism 3 includes a bearing 305. The inner ring of the bearing 305 is fitted with the outer circumferential surface of the connecting pin 301, and the outer ring of the bearing 305 is fitted with the slide groove 5. The connecting pin 301 is fixed to the rocker arm 2 by a locking nut 302. By setting the slide groove 5, the connecting pin 301, and the bearing 305, the rocker arm 2 can slide within the slide groove 5, thereby making the total length of the slide groove 5 and the rocker arm 2 adjustable, thus ensuring the stability of the rocker arm 2 in driving the door 11 to open and close.

[0039] The end of the rocker arm 2 has a connecting hole 9, which is used for the installation of the connecting pin 301. The connecting pin 301 passes through the connecting hole 9 and is locked in place by the lock nut 302.

[0040] The bearing 305 is fixed to the connecting pin 301 by a locking bolt 303, and a washer 304 is installed between the locking bolt 303 and the bearing 305. In this utility model, the connecting hole 9, the connecting pin 301, the locking nut 302, the locking bolt 303, the washer 304 and the bearing 305 are all installed concentrically.

[0041] A protrusion 306 is provided circumferentially on the outer circumferential surface of the connecting pin 301. The protrusion 306 supports the inner ring of the bearing 305, thereby separating the bearing 305 from the rocker arm 2. The protrusion 306 is used to separate the outer ring of the bearing 305 from the top wall surface of the rocker arm 2, thereby ensuring that the bearing 305 can rotate smoothly.

[0042] The rotation angle range of the lever 2 is 0°-90°. For example... Figure 5 As shown, in this utility model, in order to match the opening and closing motion of the simulated box door 11, the swing arm 2 reciprocates under the drive of the rotary cylinder 1; when the swing arm 2 rotates counterclockwise from 0° to 90° (forward rotation), the box door 11 gradually changes from the closed state to the fully open state, and the opening angle is 90°; when the swing arm 2 rotates clockwise from 0° to 90° (reverse rotation), the box door 11 gradually changes from the fully open state to the closed state.

[0043] The slide 5 adopts a groove handle. The groove handle is provided with a groove that can mate with the bearing 305, and the groove handle is a standard part, which is convenient for purchase and implementation.

[0044] In this utility model, both the groove handle and the swing rod 2 are arranged in the horizontal direction.

[0045] The input end of the rotary cylinder 1 is connected to an external air source via a connecting pipe assembly, thereby supplying air to the rotary cylinder 1. An air source processing device 6 and a solenoid valve 7 are sequentially installed on the connecting pipe assembly. The solenoid valve 7, under the action of an external controller, controls the rotation direction of the rotary cylinder 1, thus causing the rocker arm 2 to rotate forward or backward. The solenoid valve 7 is electrically connected to an external power supply and an external controller via a cable assembly. Based on the control signal from the external controller, it can change the flow direction of compressed air, thereby changing the rotation direction of the rotary cylinder 1.

[0046] The rotary cylinder 1 is provided with at least two air ports, and a speed regulating connector 8 is installed at each air port. The speed regulating connector 8 is used to connect to the connecting pipe assembly. By setting the speed regulating connector 8, the flow rate of compressed air entering the rotary cylinder 1 can be adjusted, and pipeline vibration can be prevented.

[0047] The air source treatment device 6 employs a pneumatic dual unit. This pneumatic dual unit includes a pressure reducing valve and a filter, capable of adjusting the compressed air to a suitable operating pressure range and filtering the compressed air.

[0048] The rotary cylinder 1 is fixed to the box body 10 by the cylinder bracket 4. Both the slide 5 and the cylinder bracket 4 are fixed to the wall of the fermentation box by threaded connectors; or, they can be fixed by adhesive, cable ties or other methods.

[0049] The working process of this utility model is as follows:

[0050] An external air source provides compressed air (pressure not less than 5 Bar), and the compressed air enters the rotary cylinder 1 through the connecting pipe assembly, air source treatment device 6, and solenoid valve 7 in sequence;

[0051] An external controller controls the solenoid valve 5 to reverse the compressed air supplied to the rotary cylinder 1 every 5 seconds, thereby causing the door 11 to repeatedly open and close. The test was conducted continuously for 10 days, with 10 hours of testing per day (the door 11 can be opened and closed approximately 60,000 times). During the test, the door 11 was observed to be free from damage or deformation, and the conductive membrane cable was observed to be free from damage.
